Note 2: Guaranteed by design and not production tested.
Note 3: To limit input surge currents, the current-limit threshold is set to 25% of its final value (25% x 4.8A = 1.2A) when the
MAX1536 is enabled or powered up. The current-limit threshold is increased by 25% every 256 LX cycles. The current-limit
threshold is at its final level of 4.8A after 768 LX cycles. See the Internal Soft-Start Circuit section.
Note 4: The upper and lower PGOOD thresholds are expressed as a ratio of V FB with respect to V REFIN .

Note 5: Specifications to -40°C are guaranteed by design and are not production tested.
